sega world at joypolis and others?

1) what the different between sega world at joypolis and those sega amusement centre which located at many places of Tokyo?

2) what the single game cost ( machine type ) for sega amusement centre?

thanks

Joyplis is a theme park with really some kick a** aracde but its pricy, i went there when i was in japan and i think it cost 5 usd to get in (with this card like thing) and about 5-6 bucks to play one game...i did play Initial D, the cars turn to a certian angel when u drift...really good experience...and the Club Sega are just the regular arcades, which cost 1 usd to play, and have like 4-6 floors of arcade hope this helps :)
